April 27, 2022 - A 150 degree panorama of the auroral arc across the northern sky in Alberta, Canada. The camera picked up the blue colour at the top of the curtains at left in the northwest from high-altitude sunlight illuminating the tops of the curtains. Otherwise, oxygen reds and greens dominate this fairly quiet display. Coincidentally, the arc of the aurora nicely follows the arc of the Milky Way across the north, then at its lowest for the year in the spring sky. The winter stars Castor, Pollux and Capella are setting at left; Perseus and Cassiopeia are left of centre; Cygnus (with Deneb) is rising in the northeast right of centre; Vega in Lyra is at upper right, as the summer stars rise in the northeast. Some of the lights in the distance are from farmers in the area preparing the fields for the spring seeding.
